propagation of this shellfish, and such work was undertaken in Maine 
and Massachusetts in cooperation with the State authorities. 
Pacific salmon.—Extremely satisfactory results were achieved in 
the salmon cultural work on the Columbia River. Less favorable 
conditions elsewhere on the Pacific coast resulted in a reduction in 
the output of the chinook salmon and the sockeye salmon, the most 
important species handled. Over 32,000,000 fingerlings of the two 
species were reared _to larger size before release. Salmon cultural 
operations on the Columbia River will be greatly modified by the 
program of dam construction: now approaching completion in that 
basin. The needs have been foreseen, and ample provision is being 
made to modify and enlarge operations so as to meet the new 
development. 
Anadromous species, Atlantic coast—Intense interest on the part 
of State authorities on the eastern seaboard in the perpetuation of 
the shad runs prompted more intensive effort to increase the hatchery 
output of this species. ‘This was reflected in an augmented distribu- 
tion of fry of 1814 million in comparison with the 12 million of the 
previous year. Less attention was given to the hatching of yellow 
perch, and in the case of Atlantic salmon the work was virtually dis- 
continued. This was due to inability to secure any eggs from the 
Dominion of Canada on an exchange basis as had been the case 
previously. 
Commercial species, interior waters.—There was a material increase 
in the production of whitefish fry, a total of 88,000,000 being derived 
principally from operations at the Cape Vincent, Neve station and 
at the Put in Bay, Ohio, establishment. The latter hatchery has been 
taken over by the State ‘of Ohio, which agency has assumed responsi- 
bility for the actual fish cultural work. The Bureau, however, has 
assigned certain personnel to supervise and assist in ‘the activities. 
The Duluth, Minn., station obtained limited quantities of lake trout 
and whitefish egos. As usual, the center of pike perch propagation, 
conducted in the spring months, was the Put in Bay station, the out- 
put being approximately one- -half the production of the previous year. 
A considerable number of carp fry were produced for replanting in 
the commercial fishing areas of the Mississippi River. 
Game species —The production and distribution of species which 
constitute the most prized trophies of the angler were closely com- 
parable to the record of the previous year. Brook trout were dis- 
tributed in larger numbers, and a production of 8,000,000 large and 
smallmouth bass constitutes a new record for these species. Over 
5,300,000 of these were good-size fingerlings. While the percentage 
bE fingerlings and larger fish was below that of the previous year, 
the records only cover - the size of the fish as they left the Bureau’s 
hatcheries. Millions of them were transferred to rearing pools and 
were subsequently released when they approached legal : size. It is 
regretted that there are still several sections, including the far south- 
west and central and southern Florida, which are not accessible from 
any of the existing Federal hatcheries. Only by the construction of 
new hatcheries in the areas to be served can this condition be over- 
come.
